adj. fuel pressure regulator

just failed the emissions test.
i passed by the skin of my teeth on the higher rpm test but failed on idle...
was to rich on idle.
belive me guys the cat was hot the car was running good but stil failed.
heres my question
the guy i got the car from has a aem fuel rail on it with a no name adj. fuel pressure regulator.
i wanan lean it out just enough to pass the test then turn it back and one day get it on a wide band and tune it right.
when i say "how" do i adjust it i mean does the scrue/nut/bolt need to go in or out...........i prolly need a pressure gauge on there too.

also got a ticket for the cannon...........and i think the cat is way to small....

Re: adj. fuel pressure regulator

found it on aem's website after digging for a lot longer

"""Pressure and orifice adjustments
Note: The AEM adjustable fuel pressure regulator can be fine tuned for your application. These adjustments will be covered in this section. A fuel pressure gauge needs to be used for precise tuning.
a) When fuel pressure adjustments are to be made, loosen the jam nut on the top of the AEM fuel pressure regulator and either tighten or loosen the set screw.
i) When loosening the jam nut a 3/8 wrench should be used.
ii) When tightening or loosening the set screw a 3/32 allen key should be used.
(1) To increase fuel pressure turn the set screw in a clockwise rotation.
(2) To decrease fuel pressure turn the set screw in a counter-clockwise rotation.""""".

my only thought now is that i need a gauge...
